Structure, Materials and Safety Features of Automotive Fuel Tanks

1. The automotive fuel tank is a crucial component for storing fuel, and its design directly impacts the safety and energy efficiency of the vehicle. Modern fuel tanks are usually made of multi - layer composite plastics (such as HDPE - High - Density Polyethylene) or metals (galvanized steel/aluminum alloy), taking into account both lightweight and corrosion resistance.

Industry Trends: With the development of new energy, fuel tanks are evolving towards compatibility with high - voltage hybrid systems. At the same time, the application of recyclable materials further enhances sustainability.

Core Features

1. Anti - leakage Design: The inner layer uses barrier materials (such as EVOH) to prevent fuel vapor from permeating, which complies with environmental regulations.

2. Impact - resistant Structure: Through the design of stiffeners and crush zones, the risk of rupture during collisions is reduced.

3. Integrated Components: It has built - in fuel pumps, level sensors, and ventilation systems, simplifying the assembly process.

Through the hot - plate welding process: The production of automotive fuel tanks can achieve high precision, high efficiency, and high reliability, meeting the strict requirements of new energy vehicles and traditional fuel vehicles for fuel tank sealing and corrosion resistance. In practical applications, it is necessary to combine material characteristics, workpiece structure, and production capacity requirements, optimize welding parameters, and customize equipment solutions to achieve the best production results.
